    that is, if you want the relation to be a function.

    for a relation to be a function, for one value of x ther should only be one value of x

    another way to do this is to graph it

    but seeing the set would make it easy to solve, if u draw the graph then u have to dwar a line parallel to y -axis and see at how many points the line cuts the graph...
